I have a soarer 1jz harness and on the section of wiring that has the igniter plugs, there is a 2 wire plug. i was told that i should find the sensor/switch that goes there.

i can get pictures tomorrow if needed.

just to clarify, on the section of wire harness that goes to the igniter (2 plugs) there is another 2 wire plug with a gray connector.

any help would be appreciated. thanks!
